TRIVIA: The game was initially inspired by the Neanderthal main character that graphic artist Lee Pullen doodled one day on his Atari ST. A game was designed around the main character by Chris Long and Bob Churchill and a few basic themes were further inspired by a PC Engine game called PC KID (aka B.C. KID) [Sources: CU Amiga preview (Mar 91, pp18-20); The One preview (Issue 31, Apr 91, pp29-30)].
